We arrived at the motel in mid afternoon got checked in quickly and started to settle into the room. Steve had taken care of me. The room was what they call a Jr. Suite. It had two king sized beds a couch and a couple of chairs with a TV in a sitting area a table and a huge bathroom with an enormous walk in shower. The girls started to unpack while I laid down. It was only a few minutes before I heard sounds of unhappiness. I opened my eyes and asked, "What's wrong?"

"Neither of us thought to bring a swim suit so we have to go to the beach in shorts and t shirts." Tina told me. "We just are disappointed because we wanted to get some sun. Go back to sleep, we'll wake you in an hour."

"No I'm awake, and I wanted to walk down to the liquor store anyway, to get some wine for later." Both girls brightened at the idea of sneaking alcohol as both were under the drinking age. "and soda for those who aren't 21 yet" I added, just to be a shit.

I actually had another idea. I had notice a women's clothing store about a block away when we had been driving in and I figured to surprise the girls with swim suits. I got up and headed out.

The store was well stocked, small boutique type. A little higher end than I anticipated but that's what they make credit cards for. I picked out a bikini that I new would make any red blooded male drool. It had a small triangle in the front to cover their pussies and just enough to keep from getting arrested in the back. (This was before the days of thongs and getting arrested for bearing too much was a possibility) The tops were not much more than strings with little triangles of cloth. I got two black and two white. One of each color for each girl at the same time I saw a little black dress that look so good on the mannequin that it made me horny, so I figured that it would be dynamite on the girls I got two of those also. I knew they did not have any dress clothes with them and I do like to go out for dinner and dancing when I am on vacation. I haggled with the shop owner about the price, threatening to leave it all until she knocked off 33%. She still made a bundle on me at $350 but I felt better.

When I got back to the room I handed the girls one of the bags I had. The one with the black bikinis in it and told them to try them on. Their eyes went wide when they saw them and wider still when they saw the price tags. They ran into the bathroom together and giggled and ohed and awed while they got dressed. After a few minutes Tina stuck her head out and said. "We can't wear these we'll get arrested. There's not much cloth here"

"Come on out and let me see" I answered

With that Tammy pushed past her and said "I'm not afraid!"

She was a sight! It fit perfectly. I had got a size smaller than they needed. The girls thought they were tight but every crack and crevice was visible. Perfect! Tina came out behind her sister. I paid both of them some very sincere compliments and finally Tina agreed that they did look hot. So off to the beach we went for the late afternoon sun.

I admit to feeling 10 feet tall. A beautiful scantily clad girl on each arm. I felt like a real stud. The beach was nearly empty this late in the day. We laid our towels down and headed for the water. A few minutes of splashing and dunking and generally messing around and I felt someone swim between my legs and reach up and grab my cock and pull it out of my trunks. Then Tammy surfaces in front of me. She's giggling and stroking my dick. Then just as suddenly she let go and swam away. I quickly stuffed my hardon back into my trunks and then Tina swam up to me. She put her arms around me and gave me a kiss. Then with one hand she reached down and freed my straining member. Now that it's waving in the water she slowly slid down under the water and proceeded to give me a blow job on the beach. She stayed down for as long as she could hold her breath and then surfaced again. "I'll finish that later." She said as she stuffed me back into my trunks.

Now, I was exceedingly horny, I needed to cum now! But it was not to be. Just at this time they decided to head back to the room to get some dinner. We picked up our stuff and went back to the room.

"Tammy, you get the shower first then we'll follow together, it'll be faster that way" Tina said as we entered the room.

"Your just trying to get me out of the way so you can do the nasty, but that's ok I'll co-operate" Tammy laughed in response as she ducked into the bathroom.

She wasn't wrong. As soon as the door closed I untied Tina's strings and jumped her bones. Between Tammy playing with my dick in the water and Tina sucking me off under water, not to mention the two of them looking like twins in one size to small bikinis I was more than ready.

I stuck my hand into Tina's twat and found she was as wet and ready as I was. I wasted no time in sinking my cock fully into her. She wrapped her legs around me and I plunged my meat into her until she came with a shudder and a gasp. She tried to push me off, but I wasn't done. "I want to finish what I started on the beach", she giggled at me. So I pulled out and sat on the edge of the bed while she got on her knees between my legs and took me into her mouth. She was working me expertly and I was close to cumming, then I glanced up at the bathroom door and saw Tammy peeking out watching me get my blow job. I just smiled at her as I blew my cum into Tina's mouth just as she was on the down stroke. It went right down her throat as she pulled off and took the rest in her mouth drinking every drop. As she finished Tammy quietly closed the door. She gave us just enough time to get clothes on again before shouting "I hope you to sex fiends are finished because I'm coming out." With no more warning she walked out wearing only panties and a towel in front of her drying herself.

"Tammy, put some clothes on or Jack will see you." Tina told her sister.

"Well he's already seen you and we look just alike, so what. Besides if we're going to be sharing this room for the next 4 days we will be seeing a lot of each other" Tammy answered.

"You're turning into such a slut" Tina told her.

"Just like my older sister." Tammy answered with a laugh.

Tina and I went into the bathroom and got quick showers, with only a minimum of feeling up and sucking. When we were through we pulled on our casual clothes for a walk on the boardwalk and a meal of junk food. We spent the next couple of hours walking the boards, riding the rides and eating the food. It was getting near 10 and we were all tired so we returned to the room and opened the wine I had bought for a quiet drink. Both girls thanked me for the trip and told me how wonderful I was and my head swelled so much that we were in danger of having to get another room just to fit it in. Soon the wine was gone and we were all sleepy. Tammy went to the bathroom to get changed into her oversized T shirt while Tina and I stripped down and crawled under the covers. Tina was a little apprehensive that I was sleeping nude but she didn't dwell on it as she was too tired. I dropped off instantly, even before Tammy came out of the bathroom.

As usual when I drink, I awoke about 3 hours later needing to empty my bladder and get a drink of water. I made it to the bathroom and then slid back into bed. I snuggled up against Tina and found her T shirt had ridden up over her ass. I felt my dick slide into the crack of her ass and it felt good.

I knew I was taking a chance but I reached around under her shirt and put a hand on her naked tit. I gently traced circles around her nipple and then slowly stroked over top of the tip, just teasing it. They hardened almost instantly. So I moved my hand down over her ass and to her pussy. With her legs pulled up I had easy access from the rear. I found she was wet and ready for entry as I slid a finger in and gently worked it in and out of her hole, trying to get her hotter. I met with success as she pushed her ass back against me and started to wiggle around in her sleep. I worked another finger in and then a third. Now her juices were really flowing. I pulled my fingers out and slid my dick up to her hole. Manipulating it with my hand I worked it back and forth between her lips and then slowly slid it deep inside her. She groaned with satisfaction as I slowly pumped back and forth.

I was working her into frenzy and she was still mostly asleep. So I pulled out and rolled over on my back. She whimpered at having lost what she craved and rolled over onto me. She mounted me in a second, stripped off her T shirt, and was riding me with lust filled abandon. I looked over at the other bed and saw Tammy sitting up leaning on one arm, watching us. Her other hand was buried between her legs, working her own twat while she watched her sister fuck my dick.

By now Tina was fully awake but only interested in my cock in her pussy. I looked into her eyes and said, "Tammy's awake and watching us."

"Oh Shit." was her only response as she looked over at her sister. But she didn't miss a stroke.

"Tammy if you want to see better come over here." I said.

Tammy slid right out of bed and joined us on our bed. Her face less than a foot away from my cock sliding into her sisters cunt. I reached over and turned on the bedside light and said. "Tammy if you're going to watch then get naked." She looked at me than at her sister and hesitated only a second before peeling off her shirt revealing her nakedness for all of us.

"Now lay back and keep fingering yourself so Tina can watch you." I ordered.

By now Tina was in continuous orgasm mode, just one small orgasm after another non-stop. Tammy slid up on the bed so she was next to me and was plunging her fingers into her pussy and working her clit with her thumb. I reached over and tweaked her nearest nipple with one hand while I did the same to Tina.

We kept this up for a minute or so when I moved my hand down to Tina's clit. I applied pressure and rubbed back and forth on her bud. She was building to a massive orgasm and I wanted it to be her best. At the same time I moved my other hand down to Tammy's box and stuck two fingers inside her and manipulated her clit with my thumb. She was also ready. I knew I would not last much longer either and then it came. I shot my baby juice deep into Tina's womb. The sensation of my hot cum slamming deep inside her pushed her over the edge and she came with a gush of girlcum and a scream, the sounds and smells that were released gave Tammy what she needed to finish also and she came with a shudder and a groan. We all collapsed in a heap and passed out.

I woke a few hours later with sunlight streaming into the room. I had an arm wrapped around each beautiful sister and their heads on my chest, each had a leg laying over mine, both sleeping soundly and smiling. What could be better, two beautiful sexy women in my bed sleeping contentedly. "Life is good." I thought as I dropped back off to dreamland.

I thought I was still in dreamland later when I awoke. I could feel a set of lips sliding up and down my dick and a tongue swirling around it. Over and over it was a wonderful way to wake up and I was getting used to it. I let out a groan of pleasure and the blowjob stopped for an instant and then started again as Tina wrapped her arms around me and gave me a kiss. "Wait a minute you're up here kissing me, who's sucking my cock?" even as I asked Tina the question I knew it had to be Tammy giving me the blowjob while her sister was in bed with me. I was still groggy and my brain was not quite working yet.

"I didn't think you would mind, I decided to teach Tammy how to suck cock." Tina answered. "How's she doing?"

"Either you are a great teacher or she is an excellent student." I groaned in response. "I'm not going to last much longer.

"That's OK go ahead and cum in her mouth. But wait until I get there I want to watch you blow you cum into my sister's mouth. This is so hot!" she said as she slid back down.

I pulled the sheet off so I could also see. The sight that greeted me was breathtaking. Tammy was on my right with her lips wrapped around my dick, working it up and down and Tina was on my left with her nose and mouth only inches away from my dick. I stared for a few seconds and then I felt the familiar swelling in my prick and the rushing of cum from my balls and down my shaft. Then the release as it gushed into Tammy's mouth.

"Don't swallow, hold it in your mouth." Tina ordered her sister.

I was soon finished and my dick slipped out of Tammy's mouth. She was looking at her sister with chipmunk cheeks, all puffed out. "I want to taste it too" Tina said as she leaned over and kissed her sister, opening her mouth and pushing her tongue between Tammy's lips.

Tammy hesitated at first then relaxed as Tina's tongue worked around her own as they shared my cum. They soon broke the kiss and each girl swallowed what they each had in their mouths. Tammy looked at me and like an excited kid seeking approval asked, "Did I do it right? I love sucking cock. I could have kept it up forever but I wanted to taste your cum in my mouth too."

"You did just fine and with more practice you'll be as good as your sister." I answered.

She beamed with pride at the compliment and reached over and hugged her sister to her. "Thanks for sharing Sis." Tammy said.

"Your welcome, just remember, he's mine, I got dibs. Don't try to steal him. If you want just ask." Tina answered as she hugged her sister back.

The sight of two naked women hugging each other over my naked body worked on me and my dick started to come back to life. It wasn't long before the girls noticed. It was hard not to as it rose up and poked them in the ribs.

"O good, I need to get fucked again after watching you suck him off I am so horny" Tina exclaimed as she straddled me and began to work my cock into her waiting box. She took hold of me in her had and worked my meat back and forth thru her slit teasing herself. Occasionally rubbing the head over her clit. When she was ready she sat down and impaled herself on me and began rocking back and forth. Her eyes were closed and her head tilted back as she moaned "That is so good."

Tammy crawled up next to me and lay with her head on my shoulder stroking my chest as her sister fucked me, slowly rocking back and forth. Her gaze and attention were focused on her sister, watching her sister's naked body with her perfect tits riding my cock. I took Tammy's naked ass in my hand and began stroking it. Perfect flesh so soft and willing. I moved my hand down to between her legs and she parted them for me giving me access to her wet and waiting pussy. I allowed a finger to slide into her and slowly worked it back and forth. She let out a loud sigh. We were all content each getting sexual attention, slow and gentle, lovingly.

Having just cum in Tammy's mouth, not to mention the activity of the night before, I could have kept fucking for hours without cumming again, but I could tell that Tina was getting what she needed and would soon climax so I concentrated my fingers on Tammy's G spot to increase the speed of her climax and in a few minutes both girls were creaming one into my hand and the other on my dick.

As we settled down I drew my cum covered hand to my mouth and sucked Tammy's girl cum from my fingers. Tammy watched me and finally asked "What does it taste like?" She asked me.

"Here try it." As I offered my hand to her.

She tentivly licked my fingers, Then again she licked and finally started sucking her cum off my hand. Once she had cleaned me up I asked "Since you cleaned my hand why don't you try cleaning your sister off my dick?"

She glanced at Tina for approval and received a smile and a nod. She hen wasted no time diving onto my dick and cleaning her sister's cum off of my cock and balls. When she had me cleaned up she looked at Tina and said "You taste a little different from me. Both are good but different. Is that because I'm still a virgin and your not?"

"I don't know." Tina answered. And both girls looked at me.

"All women taste a little different than each other." I said

Both girls laid down next to me and we cuddle for a while all well satisfied. After a while I reminded them that if they wanted to get any sun today we had to get our lazy asses out of bed as it was after 10AM already.

We all got up and started our morning routine, no longer worrying about who was dressed and who was in the bathroom. I was shaving when Tammy came into the bathroom and sat on the toilet to pee. As she sat there peeing and watching me Tina came in. Looked at her sister smiled and said "What a shameless slut you are becoming. Peeing in front of Jack like that. Hurry up I have to go to."

"Look who's calling who a slut." Tammy retorted. "You're the one who fucked your boyfriend while I laid in bed with the two of you, twice."

"I know, wasn't it great" Tina answered.

Both girls giggled as they switched places on the toilet and all the while I kept shaving. I still had a hardon.

Once we all finished in the bathroom the girls started to put on the suits I had gotten them the day before. I pulled the second set of suits, the white ones, out of the drawer I had hidden them in and suggested that they wear these instead.

They were thrilled and awed at getting another set of matching bikini's as another gift and I got another round of hugs and kisses as I watched their naked bodies fill the suits meager offerings. Each girl slipped on matching wraps and we were ready. I gathered up the towels and other items we needed an out we went. By this time I was hungry and we stopped at a restaurant on the way for breakfast or brunch if you would rather call it. We had a hearty and filling meal. The place was nearly empty due to the time of morning it was. There were two other couples eating at two separate tables, late risers like ourselves and a table with 8 college kids (5 boys and 3 girls) out enjoying their vacation.

I went to pay the bill and hit the head before we got to the beach and on my return I heard an interesting exchange. Apparently one of the college boys had come over to the table to try to pick my girls up once I left. I missed the opening statements but what I heard went like this

Boy: So are you girls going to join us?

Tina; No thank you. We are with someone.

Boy; Yeah I saw him. An old guy like that can't take care of you girls.

Tina: Thank you, NO. We are quite happy the way things are.

Boy; Like what is he your father or something, man he's like ancient.

Tammy; He's our boyfriend! Right Sis. We share him and he keeps us very satisfied!

Now up to this point the conversation was fairly quiet. But as the boy's eyes bugged out at Tammy's implied revelation she continued in a voice loud enough for the entire place to hear.

Tammy; Besides we didn't bring magnifying glasses so we'd never be able find you dick.

The two other couples each snickered at their tables and the boy's friends were roaring with laughter at the put down and brush off he received. I walked up behind them and said, "What's everybody laughing about? Do you girls want to back to the room for another session or to the beach for some rest?"

Tina knew I had heard at least part of the conversation so she played along by answering "You wore us out between last night and this morning we need to rest on the beach for a while." The girls rose and headed for the door. Leaving a gape mouthed college boy behind. I dropped a couple of bucks on the table for a tip and looked at him. "Don't worry son, one day you'll grow up to be a man and have beautiful women too." At that his friends started laughing all over again and the other couples in the restaurant were near hysterics as I walked out.

What shocked me most was the way Tammy had referred to me as "our boyfriend" and since Tina had not even flinched when she said it I could only surmise that, sometime earlier the girls had decided to share me, not that I was complaining. My only real worry was that I would survive the continued sexual use.
